## Indications for Use

The Smith & Nephew LEVELERT II Fluid Level Sensor is intended to weigh a bag of irrigation fluid and signal operating room personnel when a pre-determined amount of fluid remains.

## Device Story

Levelert II is a stand-alone, DC battery-powered, non-rechargeable electronic monitor used in arthroscopic procedures. It functions by weighing a bag of irrigation fluid via an internal load cell. The device incorporates an internal microprocessor to process weight data against user-selected pre-determined thresholds. When the fluid level reaches the set limit, the device signals operating room personnel. This feedback allows clinicians to manage irrigation fluid supply during surgery, potentially preventing fluid depletion. The device is operated by OR staff; it replaces previous designs that utilized external power supplies and external microprocessors.

## Clinical Evidence

Bench testing only. Performance, EMI/EMC, and UL safety testing, along with software verification and validation, were conducted to demonstrate substantial equivalence to the predicate device.

## Technological Characteristics

Stand-alone, DC battery-powered, non-rechargeable electronic monitor. Features an internal load cell for weight sensing and an integrated microprocessor. User interface utilizes dome switches. Designed for use in arthroscopic procedures.

## Regulatory Identification

An electronic monitor for gravity flow infusion systems is a device used to monitor the amount of fluid being infused into a patient. The device consists of an electronic transducer and equipment for signal amplification, conditioning, and display.

## Predicate Devices

- Smith & Nephew Dyonics Levelert System ([K912453](/device/K912453.md))

#### D. Predicate Devices

The predicate device for the Levelert II is the current Smith & Nephew Dyonics Levelert System cleared in K912453.

#### Description of Device E.

The Levelert II is a irrigation fluid bag level sensing device designed to provide the user with fluid level feedback at pre-determined values. The pre-determined values are selected by the user. The Levelert II is a stand-alone DC battery powered, nonrechargeable device that is used in arthroscopic procedures.

#### F. Intended Use

The Smith & Nephew Levelert II Fluid Level Sensor is intended to weigh a bag of irrigation fluid and signal operating room personnel when a pre-determined amount of fluid remains.

## G. Comparison of Technological Characteristics

The Levelert II has the same Indications for Use as the predicate device, utilizes the same operating principle, incorporates the same basic design, and is manufactured under a Quality System.

The differences between the Dyonics Levelert System and the Levelert II are the additional of a battery to power the device instead of an external power supply, the use of a load cell instead of a spring loaded circuit design, dome switches instead of an adjusting knob and incorporating the microprocessor internally instead of externally connecting to one.

## H. Summary Performance Data

The performance testing, EMI/EMC testing, UL Safety testing and the software verification and validation conducted on the Levelert II demonstrates substantial equivalence to the Dyonics Levelert System cleared in K912453. The testing also demonstrates that the differences in the new device and the predicate device do not raise any new issues of safety and efficacy and that the Levelert II performs as well as the legally marketed device.
